DESCRIPTION & OPERATION

With the ignition switch in RUN position, battery voltage is

applied to the master power window switch located on the driver’s

door. The master power window switch provides power and ground for all

power window switches and motors. The master power window switch

offers one-touch operation of driver’s window. A solid state control

unit, incorporated in the master switch, fully lowers driver’s window

when switch is completely depressed. Master switch also includes lock-

out feature to prevent passengers from operating any of the other

power window door switches.

TROUBLE SHOOTING

POWER WINDOWS INOPERATIVE

Check for faulty sub fusible link No. 10, faulty power window

relay or faulty power window switches.

ONE WINDOW FAILS TO OPERATE

If one window does not operate, even if both master and

passenger side power window switches are pressed, check for faulty

master power window switch or power window motor that is inoperative.

If one window does not operate, only when either master or passenger

side power window switch is pressed, but does operate when both

switches are pressed, check power window switch that is inoperative.

ONE-TOUCH SWITCH FUNCTION INOPERATIVE

Replace master power window switch.

TESTING

CIRCUIT BREAKER TEST

Press UP switch to fully close window. Continue to press

switch for 10 seconds. Release UP switch and immediately press DOWN

switch. If window begins to open within 60 seconds, circuit breaker is

okay. Circuit breaker is part of window motor.

POWER WINDOW RELAY TEST

1) Remove power window relay from fuse/relay block, located

in engine compartment. See Fig. 1. Check continuity between power

window relay terminals No. 2 and No. 4. Continuity should be present.

2) Connect positive lead of a 12-volt battery to power window

relay terminal No. 2, and negative lead of test battery to terminal

No. 4. See Fig. 2. Continuity should be present between terminals No.

1 and No. 3 with voltage applied. Replace power window relay if

continuity is not as specified.

POWER WINDOW MOTOR TEST

1) Remove appropriate door trim panel. Connect positive lead

of a 12-volt test battery to either motor terminal. Connect negative

lead of test battery to other motor terminal. Motor should operate,

unless it is already at maximum travel.

2) Reverse test battery leads. Motor should operate in

opposite direction. If motor does not operate, inspect wiring. If

wiring is okay, replace motor. Reverse test battery leads again to

complete full function test of motor.

POWER WINDOW SWITCH TEST

Remove control switch from trim panel. Using ohmmeter, check

continuity of switch. See appropriate WINDOW SWITCH CONTINUITY CHART.

See Figs. 3-5. Replace appropriate switch as necessary if switch

continuity is not as specified.
